/login URL broken

On a typical WordPress install with a good web hosting provider, all you need to do is add /login/ or /admin/ to the end of your site URL.
For example: https://www.example.com/admin/
https://www.example.com/login/

Both of these URLs will redirect you to the WordPress login page. If for some reason, your WordPress login URL is not working properly, then you can easily access the WordPress login page by going to this URL:
https://www.example.com/wp-login.php

Thank you wiseshop. The point is that the /login/ url points to the wrong place, and I want to reset it to wp-login.php

I need to give my users the /login/ url, and not the wp-login.php

How can I do this?
